#1: Odd misfire :-/ Author: sicskate, Location: Margate, KentPosted: Fri Jun 24, 2011 11:51 am ---- This only started this evening on my 138gti
When between 1750-2250 rpm I'm getting a miss fire and a flatspot.
Its not too bad as I can just accelerate through it, but it's a pain as between gear changes it usually picks up at around 2000rpm, so every gear change I'm getting this, unless I'm giving it beans.
Many thanks in advance.

#3: Re: Odd misfire :-/ Author: sicskate, Location: Margate, KentPosted: Fri Jun 24, 2011 12:00 pm ---- Nope, the bulb only comes on with the ignition on.
#4: Re: Odd misfire :-/ Author: MrBSI, Location: What's it to you? ? ?Posted: Fri Jun 24, 2011 12:16 pm ---- Might be worth checking / replacing the spark plugs first.
Nice set of Bosch super plus plugs are cheap enough.
Hope it aint running NGK's
#5: Re: Odd misfire :-/ Author: roberto.f, Location: Coventry/ManchesterPosted: Fri Jun 24, 2011 12:18 pm ---- Could be loads of things. Injectors faulty, lambda, coil pack, spark plugs, list goes on..
#6: Re: Odd misfire :-/ Author: sicskate, Location: Margate, KentPosted: Fri Jun 24, 2011 12:21 pm ---- Yup, I'm aware it could be a number of things.
Luckily I'm quite handy with tools, I mainly wanted to rule out a clutch issue as it's always between the same rpm.

#9: Re: Odd misfire :-/ Author: sicskate, Location: Margate, KentPosted: Fri Jun 24, 2011 2:20 pm ---- Does that mean I have to take it to a garage?
#10: Re: Odd misfire :-/ Author: GTINI, Location: Northern IrelandPosted: Fri Jun 24, 2011 3:54 pm ---- I had a similar problem. My car started to misfire and one of my mates said it might have been my HT leads or spark plugs. So we changed the sparks to super 4's but that didn't solve the problem. My uncle then did a diagnostics and found that an injector was the problem. After a few weeks, the same again, one of the other injectors had gone. Then it misfied again so I had enough, it needed serviced anyway so sent it into puegeot to see what the crack was and they serviced it. I felt stupid after, the sparks plugs wern't tightened so when accelerating they where bouncing out and causing a misfire (wasn't me that change the sparks lol). But the original problem was the injector but thats what can happen so get everything checked. Also maybe check the coil pack, changed it too but it wasn't that lol. Hope that helps a bit.

take it a garage, get the fault codes read, then you'll know exactly what todo
#13: Re: Odd misfire :-/ Author: Rob2859, Location: HalifaxPosted: Sat Jun 25, 2011 4:12 am ---- A decent garage will charge nothing or very little to plug a diagnostic machine in. You may need to get the error log cleared before the light goes out.

#18: Re: Odd misfire :-/ Author: sicskate, Location: Margate, KentPosted: Sun Jun 26, 2011 10:26 am ---- Car won't even start now... Turns over nicely.
I'm guessing the coilpack is brown bread?
#19: Re: Odd misfire :-/ Author: Lee, Location: EnglandPosted: Sun Jun 26, 2011 10:27 am ---- sure its not the immo now?
get it scanned, instead of throwing parts at it
#20: Re: Odd misfire :-/ Author: sicskate, Location: Margate, KentPosted: Sun Jun 26, 2011 10:32 am ---- I can't get it tested unless I get it transported to a garage as its stuck at the back of my drive.
Is there anyway around an immobiliser issue?
#21: Re: Odd misfire :-/ Author: Lee, Location: EnglandPosted: Sun Jun 26, 2011 10:34 am ---- Try the spare key
#22: Re: Odd misfire :-/ Author: sicskate, Location: Margate, KentPosted: Sun Jun 26, 2011 10:37 am ---- Lost it a few weeks back when moving house

No fuel getting to the rail.
So guessing you are correct.
Are there any other ways around this, or will I have to order a new key and post it to you ect?
#24: Re: Odd misfire :-/ Author: Lee, Location: EnglandPosted: Sun Jun 26, 2011 1:39 pm ---- You've not hit the fuel cut off switch have you? Big red/black button behind the battery
#25: Re: Odd misfire :-/ Author: sicskate, Location: Margate, KentPosted: Sun Jun 26, 2011 1:53 pm ---- Nope, not that I know of.
It was running last night, didn't touch it untill this morning.
#26: Re: Odd misfire :-/ Author: MrBSI, Location: What's it to you? ? ?Posted: Mon Jun 27, 2011 7:58 am ---- Ignition OFF but key in barrel, open drivers door & listen.
If you can hear a beep then the immobiliser should be working correctly.
Doubly relay is also favourite on this non plexed 206's, think it lives under the engine ecu.
Crank sensor is also a likely failure as well.
#27: Re: Odd misfire :-/ Author: sicskate, Location: Margate, KentPosted: Mon Jun 27, 2011 12:22 pm ---- Ok... I Turned it over this evening and no fire.
Left the key in the car, tried again 10 mins later and it's alive!
But now the rad temp guage is being gay.
It's flipping round 3 times on start up, reading abit high and the fan is on even when I can grab the rad pipes and touch the head with my hand.
Possible thermostat or rad temp sensor??
